T 0 all whom it may concern."

Be it known that I, CHARLES R. BROOKS, a citizen of the United States, residing at Little Falls, in the county of Morrison, State of Minnesota, have invented certain new and useful Improvements in Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to new and useful improvements in ventilators and it has particular reference to a ventilator constituting an attachment to a stove pipe and soconstructed and arranged with relation thereto that a forced draft is created whereby all impurities are removed from the room.

In connection with a ventilator of the above type, the invention aims as a primary object to provide a novel construction, combination and arrangement of parts, the details of which will appear in the course of the following description in which reference is had to the accompanying drawings forming a part of this specification, like characters of reference designating similar parts throughout the several views wherein Figure 1 is a side elevation of a ventilator constructed in accordance with the present invention and showing its application to a stove ipe of ordinary construction. Fig. 2 is a p an view thereof. Fig. 3 is a central longitudinal section thereof, and Fig. 4 is a horizontal section on the line 4 4 of Fig. 3.

Referring specifically to the accompanying drawings, the numeral 1 designates a stove pipe and the numeral 2 ventilators constructed in accordance with the present invention and applied to the pipe 1 at each side thereof. The ventilators 2 are counterparts in construction and a description of a single ventilator will be applicable to both. The ventilator 2 comprises a conductor 3 of suitable sha e and having closed ends and an open side a j acent the stove pipe, whereby said pipe constitutes one side of said conductor. The conductor 3 has a flange 4 circumscribing the edges thereof, rivets or other fastening means 5 being passed through said flange to fix the conductor to the pipe 1.

l/Vithin the conductor 3 is a longitudinal partition 6, dividing the interior of the conductor into outer and inner chambers 7. The outer wall 9 of the conductor 3 has respective upper and lower openings 10 and 11 therein which communicate with the room and adjacent which are mounted funnels 1.2 for collecting the air from the room and directing it into said conductor.

The inner chamber above referred to is designated by the numeral 7 and the outer chamber is subdivided by horizontal partitions 13 into chambers 14, 15 and 16 arranged one above the other and constituting air passages. As shown only the chambers 14 and 15 are employed but upon the addition of another funnel the chamber 16 may be likewise employed. The partitions 13 occur at points between the severally adjacent funnels, the arrangement being such that the opening 10 communicates with the passage 14 and the opening 11 with the passage 15. The passages 14 and 15 communicate by means of respective o enings 16 and 17 in the partition 6 with t 1e chamber 7 and the latter in turn communicates with the interior of the pipe 1 by an opening 18 provided therein. In Fig. 3, it will be noticed that the openings 18 at each side of the pipe 1 are in non-alined relation. This arrangement is preferred in order that the suction or draft of one ventilator may not influence the suction or draft of the other. here more than two ventilators are employed the openings 18 are arranged in stepped relation to accomplish the same object.

The direction of travel of the air currents is indicated by the arrows in Fig. 3 in which it will be noted that the air currents simultaneously enter the conductor through the openings 10 and 11 and pass through the respective passages 14 and 15 and openings 16 and 17 and from thence through the opening 18 to the interior of the pipe 1. The partitions 13 thus serve to prevent communication between the passages 14 and 15, in which function they coact with the walls adjacent thereto to afford seals. It is obvious that the number of passages similar to the passages 14 and 15 may be increased as desired by increasing the various openings and partitions 13 without disturbing the arrangement above described. It is to be noted that the conductor 3 forms the side walls for the various passages and chambers referred to in the foregoing description and that the vertical outer walls of said conductor prevent the device from having an unsightly appearance.

From the foregoing description it will be seen that simple and efficient means are provided for accomplishing the objects of the invention but while the elements herein shown and described are well adapted to serve the functions set forth it is obvious that various minor changes may be made in the proportions, shape, and arrangement of the several parts without departing from the spirit and scope of the invention as defined in the appended claims.

What is claimed is:

1. A ventilator of the class described comprising the combination with a stove pipe, of a conductor, a longitudinal partition in said conductor dividing the same into separate chambers, said conductor having openings in one of its walls arranged at determinate intervals, and partitions in one of said chambers dividing the same into air passages sev erally having communication with said last named openings, said longitudinal partition having openings therein severally affording communication between said respective air passages and the other of said chambers, said stove pipe having an opening therein communicating with said last named chamber.

2. A ventilator of the class described comprising the combination with a stove pipe, of a conductor, a longitudinal partition in said conductor dividing the same into separate chambers, said conductor having openings arranged in one of its walls at determinate intervals, funnels secured adjacent said respective openings and communicating severally therewith and partitions in one of said chambers dividing the same into air passages severally having communication with said last named openings, said longitudinal partition having openings therein severally affording communications between said re spective air passages and the other of said chambers, said stove pipe having an opening therein communicating with said last named chamber.

3. A ventilator of the class described comprising the combination with a stove pipe having an opening therein, of a conductor having an air chamber communicating with said opening, said conductor being provided with air passages independent of one another and having individual communication with said air chamber and with the exterior ofsaid conductor.

4. A ventilator of the class described comprising the combination with a stove pipe having an opening therein, of a conductor having an air chamber communicating with said opening, said conductor being provided with air passages independent of one another and having individual communication with said air chamber and with the exterior of said conductor, and funnels carried by the conductor and communicating with said respective air passages from the exterior thereof.

5. A ventilator of the class described comprising a stove pipe having non-alined openings therein and independent conductors severally communicating with said openings, said conductors also having communication with the exterior thereof.

In testimony whereof, I affix my signature, in presence of two witnesses.
